Overview of Information Processing Apparatus According to         Embodiment of the Present Disclosure>

First, an overview of an information processing apparatus according to an embodiment of the present disclosure will be described with reference to FIG. 1. FIG. 1 is a diagram for describing the overview of the information processing apparatus according to the embodiment of the present disclosure.

An information processing apparatus 100 includes a display unit 112 and displays content on the display unit 112. The information processing apparatus 100 displays objects used to select content displayed on the display unit 112 on the display unit 112. For example, the objects can be thumbnails corresponding to the content. Therefore, the information processing apparatus 100 can display the thumbnails while displaying the content.

For example, as illustrated in FIG. 1, the information processing apparatus 100 can display the content on the display unit 112 and display thumbnails A to E used to select content to be displayed in a superimposed manner.

Here, when there are a plurality of pieces of display target content, the number of thumbnails to be displayed increases according to the number of pieces of content. When the number of thumbnails increases, a user performs a complicated operation such as an operation of confirming the thumbnails one by one to retrieve content which the user desires to view. On the other hand, when display of content being reproduced is hidden to retrieve the content, convenience for the user may be impaired. Accordingly, the information processing apparatus 100 determines a category to which display target content belongs and displays thumbnails (hereinafter also referred to as thumbnails corresponding to a category) corresponding to the content belonging to one category, while the content being reproduced is displayed. Further, the information processing apparatus 100 switches one category to which the content corresponding to the thumbnails to be displayed belongs according to a user's operation.

For example, the information processing apparatus 100 displays thumbnails A to E belonging to one certain category (“Category 1”). When the user performs an operation of switching a category, the information processing apparatus 100 displays the thumbnails corresponding to the content belonging to the category “Category 1” being displayed and thumbnails of content belonging to a switching destination category.

Thus, the information processing apparatus 100 according to the embodiment of the present disclosure displays the thumbnails corresponding to the content belonging to the one category, while displaying the content, and switches the one category to which the content corresponding to the thumbnails being displayed belongs according to the user's operation. Therefore, the user can confirm the thumbnails corresponding to the content according to a category without his or her convenience being impaired, and thus efficient content retrieval is possible. In FIG. 1, a television receiver is illustrated as an example of the information processing apparatus 100. However, the information processing apparatus 100 may be a tablet terminal, a personal computer, or the like.

<2. Embodiment of the Present Disclosure>

[2-1. Configuration of Information Processing Apparatus According to Embodiment]

The overview of the information processing apparatus 100 according to the embodiment of the present disclosure has been described above. Next, the configuration of the information processing apparatus 100 according to the embodiment of the present disclosure will be described with reference to FIG. 2. FIG. 2 is a block diagram illustrating a schematic functional configuration of the information processing apparatus 100 according to an embodiment of the present disclosure.

As illustrated in FIG. 2, the information processing apparatus 100 includes a controller communication unit 102, an operation detection unit 104, a server communication unit 106, a category determination unit 108, a display control unit 110, and a display unit 112.

The controller communication unit 102 communicates with a remote controller 200 which is operated by the user. Specifically, the controller communication unit 102 receives operation information which is information regarding the information processing apparatus 100 and is transmitted from the remote controller 200. For example, the controller communication unit 102 can communicate with the remote controller 200 using short range wireless communication such as infrared rays, Bluetooth (registered trademark), or WiFi (registered trademark). The remote controller 200 can be a touch pad type or button type remote controller.

The operation detection unit 104 detects operation details on the information processing apparatus 100. Specifically, the operation detection unit 104 detects operation details based on the operation information which is the information regarding the information processing apparatus 100 and is received by the controller communication unit 102.

The server communication unit 106 communicates with a content server 300 that delivers content. Specifically, the server communication unit 106 acquires display target content and content information from the content server 300 through communication. The content information can include text information indicating an overview or the like of the content, category information to which the content belongs, and thumbnails. The content server 300 delivers content corresponding to an acquisition request from the server communication unit 106.

The category determination unit 108 determines a category to which the content acquired by the server communication unit 106 belongs. Specifically, the category determination unit 108 determines a category to which the content belongs with reference to the category included in the content information acquired along with the content by the server communication unit 106. For example, the category can be current broadcast progress, favorites, terrestrial digital television broadcast, moving-image delivery from the Internet, or the like.

The display control unit 110 causes the display unit 112 to display the content and thumbnails corresponding to reproducible content according to a user's operation. Specifically, when the operation detection unit 104 detects a content display operation, the display control unit 110 displays content using the entire display screen of the display unit 112 as a display region. When a thumbnail display operation is detected by the operation detection unit 104, the display control unit 110 displays thumbnails of content belonging to one category so that the thumbnails are superimposed on the content being displayed. When the operation detection unit 104 detects a category switching operation, the display control unit 110 moves the thumbnails being displayed in a vertical direction with respect to an arrangement direction of the thumbnails and changes thumbnails to be displayed to thumbnails of content belonging to a switching destination category. The foregoing thumbnail display process will be described in detail with reference to FIG. 3. FIG. 3 is an image diagram for describing an example of a thumbnail display process of the information processing apparatus 100 according to the embodiment.

(Thumbnail Display Process)

First, when the user performs a thumbnail display operation, the display control unit 110 acquires thumbnails of content belonging to one category set in initial display. For example, as illustrated in FIG. 3, when the thumbnail display operation is detected by the operation detection unit 104, the category determination unit 108 determines a category with reference to the category information included in the content information and specifies content belonging to the category “Category 1”. Then, the display control unit 110 acquires thumbnails 1A to 1D of the specified content from the content information.

Next, the display control unit 110 causes the display unit 112 to display a category name and the acquired thumbnails. For example, as illustrated in FIG. 3, the display control unit 110 can cause the display unit 112 to display the category name “Category 1” and the acquired thumbnails 1A to 1D of the content belonging to the category “Category 1”.

Next, when the user performs a category switching operation, the display control unit 110 acquires thumbnails of content belonging to a switching destination category. For example, when the operation detection unit 104 detects an operation of switching the category to a subsequent category “Category 2” illustrated in FIG. 3, the category determination unit 108 determines a category with reference to the category information and specifies content belonging to the category “Category 2.” Then, the display control unit 110 acquires thumbnails 2A to 2C of the specified content from the content information.

The display control unit 110 switches the category name and the thumbnails to be displayed to the switching destination category name and the acquired thumbnails of the content belonging to the switching destination category. For example, the display control unit 110 can move the thumbnails 1A to 1D of the content belonging to the category “Category 1” illustrated in FIG. 3 to the middle of the screen to erase these thumbnails from the display screen and cause the display unit 112 to display the acquired thumbnails 2A to 2C of the content belonging to the category “Category 2” shown below the category “Category 1” of FIG. 3.

The thumbnail display operation and the category switching operation can be, for example, flicking operations in the touch pad type remote controller 200 or operations of pressing category switching buttons in the button type remote controller 200. For example, when the thumbnails are displayed as in FIG. 3, the display control unit 110 displays the thumbnails 1A to 1D corresponding to the content belonging to the category “Category 1” through an upward flicking operation on the touch pad type remote controller 200. When an upward flicking operation is further performed, the display control unit 110 switches the category to the category “Category 2” and displays the thumbnails 2A to 2C. When the thumbnails 2A to 2C are displayed and a downward flicking operation is performed in this state, the display control unit 110 switches the category to the immediately previous category “Category 1”. When thumbnails set as initial display are displayed and a thumbnail display operation is performed in this state, the display control unit 110 ends the display of the thumbnails. For example, when the thumbnails are displayed as in FIG. 3 and a downward flicking operation is performed in the display state of the thumbnails 1A to 1D corresponding to the content belonging to the category “Category 1”, the display control unit 110 ends the display of the thumbnails.

(Display Region of Thumbnails)

The display control unit 110 displays the thumbnails in a narrow region in the display screen. Specifically, the display control unit 110 displays the thumbnails in one direction along one side of the display screen in a region which is a region located distant from the middle of the display screen and is a smaller region than a display region of the content displayed on the display screen. For example, as illustrated in FIG. 1, the display control unit 110 can display the thumbnails A to E in the horizontal direction along the lower side of the display screen in a region which is a region located below the middle of the display screen and is a smaller region than the display region of the content displayed on the display screen. Therefore, it is possible to display the thumbnails without interfering with the display of the content being reproduced.

(Focus Display of Thumbnail)

The display control unit 110 performs display to clearly show a selected thumbnail. Specifically, the display control unit 110 brings a thumbnail into focus closer to a display position of an operation object moved on the display screen according to a user's operation than the other thumbnails. For example, focus display of a thumbnail will be described with reference to FIG. 4. FIG. 4 is a diagram illustrating focus display for thumbnails of the information processing apparatus 100 according to the embodiment.

The display control unit 110 brings a thumbnail into focus 20 closer to a display position of an operation object, e.g., a cursor, than the other thumbnails. For example, as illustrated in the left drawing of FIG. 4, the display control unit 110 brings the thumbnail 1C into focus 20 closer to the display position of the cursor 10 than the other thumbnails, among the displayed thumbnails 1A to 1D. As illustrated in the right drawing of FIG. 4, the display control unit 110 brings the thumbnail 1B into focus 20 when the display position of the cursor 10 is changed and the thumbnail closer to the display position of the cursor 10 than the other thumbnails is changed to the thumbnail 1B. Therefore, since the user can select the thumbnail brought into focus 20 while confirming the display position of the cursor 10, it is possible to improve operability. In FIG. 4, the focus 20 is expressed by displaying the frame of the thumbnail thicker than those of the other thumbnails, but an embodiment of the present disclosure is not limited thereto. The focus 20 can be expressed by allowing the luminance of the frame of the thumbnail to be higher than that of the other thumbnails or allowing the color of the frame of the thumbnail to be different from those of the other thumbnails.

The example in which the display of the focus 20 is performed based on the display position of the cursor 10 has been described above. However, the display of the focus 20 may be changed based on a movement amount of an operator detected by the operation detection unit 104. Specifically, when a movement amount of an operator detected by the operation detection unit 104 exceeds a predetermined amount, the display control unit 110 brings a thumbnail into focus 20 adjacent to the thumbnail brought into focus 20 in a movement direction of the operator of the thumbnail. For example, when a movement amount of a finger touching an operation surface of the touch pad type remote controller 200 exceeds a predetermined amount, the display control unit 110 moves the focus 20 to a thumbnail adjacent to the thumbnail brought into focus 20 in a movement direction of the finger. Therefore, the thumbnail brought into focus 20 can be changed without displaying the operation object such as the cursor 10. The display of the focus 20 may be changed by pressing a button of the remote controller 200.

(Scrolling of Thumbnails)

The display control unit 110 performs scrolling of the thumbnails according to a user's operation. Specifically, the display control unit 110 displays an operation object, e.g., the cursor 10, moving on the display screen according to a user's operation. When an operation of placing the cursor 10 at an end region of the display screen in a scrolling direction is performed, the thumbnails of a category corresponding to the displayed thumbnail are scrolled. For example, a thumbnail scrolling process will be described with reference to FIG. 5. FIG. 5 is a diagram illustrating scrolling of the thumbnails of the information processing apparatus 100 according to the embodiment.

First, the display control unit 110 determines whether the display position of the cursor 10 is located at an end region of the display screen. For example, as illustrated in the left drawing of FIG. 5, the display control unit 110 can set end regions in a length direction of the display screen including regions from the ends of the display screen to position (positions of imaginary lines in the left drawing of FIG. 5) of 10% of the length in the length direction of the display screen, as predetermined regions and determine whether the display position of the cursor 10 is inside one of the predetermined regions.

Next, when the display control unit 110 determines that the display position of the cursor 10 is located in one of the end regions of the display screen, the display control unit 110 performs the scrolling of the thumbnails. For example, as illustrated in the right drawing of FIG. 5, when the display control unit 110 determines that the display position of the cursor 10 is located inside one of the above-described predetermined regions, the display control unit 110 moves the displayed thumbnails 1A to 1D in the horizontal direction toward an end of the display screen opposite to the end of the display screen close to the display position of the cursor 10. Then, the display control unit 110 moves the thumbnails 1A to 1D and displays the thumbnail 1E adjacent to the thumbnail 1D while moving the thumbnail 1E.

Thus, the display control unit 110 scrolls the thumbnails when an operation of placing the cursor 10 at an end region of the display screen in the scrolling direction is performed. Therefore, the user can scroll the thumbnails intuitively. The example in which the scrolling is performed when the display position of the cursor 10 is in the end region of the display screen has been described above, but the scrolling may be performed through a drag operation by the touch pad type remote controller 200. For example, when the user performs a drag operation with two of his or her fingers on the touch pad of the touch pad type remote controller 200, the operation detection unit 104 detects this operation and the display control unit 110 performs the scrolling process.

The display control unit 110 allows a movement speed of the thumbnail to be faster when the position of the operation object is a position closer to an end of the display screen in the end region of the display screen in the scrolling direction. For example, the display control unit 110 allows the movement speed of the thumbnail to be faster when the display position of the cursor 10 illustrated in the left drawing of FIG. 5 is a position closer to the end of the display screen than the position of 10% of the length of the display screen from the end of the display screen in the length direction. Therefore, by changing a scrolling speed according to the display position of the cursor 10, the user can adjust the scrolling speed intuitively.

(Thumbnail Selection Process)

When a thumbnail selection operation is performed, the display control unit 110 ends the display of the thumbnails and switches the display of the content being reproduced to content corresponding to the thumbnail subjected to the selection operation. Specifically, when the operation detection unit 104 detects a thumbnail selection operation, the display control unit 110 ends the display of the thumbnails, acquires content corresponding to the thumbnail subjected to the selection operation, and displays the acquired content. For example, the thumbnail selection operation can be a pushing operation on the touch pad or a tapping operation on the touch pad. The thumbnails can be moved and erased in a direction oriented away from the middle of the screen.

Here, when the configuration of the information processing apparatus 100 is described again with reference to FIG. 2, the display unit 112 displays the content and the thumbnails corresponding to the content under the control of the display control unit 110.

[2-2. Process of Information Processing Apparatus According to Embodiment]

Next, a process of the information processing apparatus 100 according to the embodiment will be described with reference to FIG. 6. FIG. 6 is a flowchart conceptually illustrating a process of the information processing apparatus 100 according to the embodiment. The repeated description of the configuration of the above-described information processing apparatus 100 will be omitted.

First, the display control unit 110 waits until an upward flicking operation or an operation of pressing a display button is performed (step S402). Specifically, the display control unit 110 waits until the operation detection unit 104 detects the upward flicking operation or the operation of pressing the display button based on operation information received by the controller communication unit 102.

When the upward flicking operation or the operation of pressing the display button is performed in step S402, the display control unit 110 displays thumbnails (step S404). Specifically, when the operation detection unit 104 detects the upward flicking operation or the operation of pressing the display button, the display control unit 110 causes the display unit 112 to display the thumbnails corresponding to a category set in initial display.

Next, the display control unit 110 determines whether a return button is pressed (step S406). Specifically, when the operation detection unit 104 detects the pressing of the return button, the display control unit 110 determines that the return button is pressed.

When the display control unit 110 determines in step S406 that the return button is pressed, the display control unit 110 erases the thumbnails (step S408). Specifically, the display control unit 110 erases the displayed thumbnails from the display screen and ends the thumbnail display process.

When the display control unit 110 determines in step S406 that the return button is not pressed, the display control unit 110 determines whether a downward flicking operation is performed (step S410). Specifically, when the operation detection unit 104 detects the downward flicking operation, the display control unit 110 determines that the downward flicking operation is performed.

When the display control unit 110 determines in step S410 that the downward flicking operation is performed, the display control unit 110 determines whether the category is an uppermost category (step S412). Specifically, the display control unit 110 determines whether the category corresponding to the displayed thumbnails is the category set in the initial display. When it is determined in step S412 that the category is the uppermost category, the process proceeds to step S408.

When the display control unit 110 determines in step S410 that no downward flicking operation is performed, the display control unit 110 determines whether an upward flicking operation is performed (step S414). Specifically, when the upward flicking operation is detected, the display control unit 110 determines that the upward flicking operation is performed.

When the display control unit 110 determines in step S414 that the upward flicking operation is performed or determines in step S412 that the category is not the uppermost category, the display control unit 110 switches the category (step S416). Specifically, the display control unit 110 switches the displayed thumbnails to thumbnails corresponding to a switching destination category.

When the display control unit 110 determines in step S414 that no upward flicking operation is performed, the display control unit 110 determines whether a left dragging operation or a right dragging operation is performed (step S418). Specifically, when the operation detection unit 104 detects a right or left dragging operation, the display control unit 110 determines that the right or to left dragging operation is performed.

When the display control unit 110 determines in step S418 that the left dragging operation or the right dragging operation is performed, the display control unit 110 determines whether the cursor 10 is located in a predetermined region of an end of the screen (step S420). For example, the display control unit 110 can determine whether the display position of the cursor 10 is located at an end of the display screen with respect to the position of the display screen stored in advance in a storage unit (not illustrated) included separately in the information processing apparatus 100.

When the display control unit 110 determines in step S420 that the cursor 10 is located in the predetermined region of the end of the screen, the display control unit 110 scrolls the thumbnails (step S422). Specifically, the display control unit 110 scrolls the thumbnails of the category corresponding to the displayed thumbnails.

When the display control unit 110 determines in step S420 that the cursor 10 is not located in the predetermined region of the end of the screen, the display control unit 110 determines whether the display position of the cursor 10 is moved to another thumbnail (step S424). Specifically, the display control unit 110 determines whether the thumbnail closer to the display position of the cursor than the other thumbnails is different from the thumbnail brought into focus 20.

When the display control unit 110 determines in step S424 that the display position of the cursor 10 is moved to another thumbnail, the display control unit 110 moves the focus 20 (step S426). Specifically, the display control unit 110 changes the thumbnail brought into focus 20 to the thumbnail closer to the display position of the cursor 10 than the other thumbnails.

After the processes of steps S416, S422, and S426 are performed or when it is determined in step S418 that the left or right dragging operation is not performed, the process returns to step S406.

Thus, in the embodiment of the present disclosure, the thumbnails corresponding to the content belonging to one category are displayed while displaying the content, and the displayed thumbnails are moved according to an operation of switching the one category to which the content corresponding to the displayed thumbnails belongs. Therefore, since the user can confirm the thumbnails corresponding to the content according to the category without his or her convenience being interfered with, the efficient content retrieval is possible. Further, since the thumbnails are moved and the category is switched, it is possible to provide a comfortable operation to the user.

[2-3. Modification Examples of Embodiment]

The first embodiment of the present disclosure has been described above. The embodiment is not limited to the above-described example. First to seventh modification examples of the embodiment will be described below.

(First Modification Example)

The display control unit 110 according to the first modification example of the embodiment may display thumbnails so that a user can recognize a group to which content corresponding to the thumbnails belongs. Specifically, the display control unit 110 displays an object indicating a group in the periphery of the thumbnails corresponding to the content belonging to the group. For example, a group display process will be described with reference to FIG. 7. FIG. 7 is a diagram illustrating group display in the information processing apparatus 100 according to the first modification example of the present embodiment.

First, after the display control unit 110 acquires thumbnails through the thumbnail display operation performed by the user, the display control unit 110 determines a group of the acquired thumbnails. For example, the category determination unit 108 determines the category with reference to the category information and specifies the content belonging to the category “Category 1” illustrated in FIG. 7. Then, the display control unit 110 determines the group to which the specified content belongs based on group information included in the content information. The group information includes a group name.

Next, the display control unit 110 acquires the thumbnails and the group name to which the thumbnails belong from the group information and causes the display unit 112 to display the acquired group name. For example, as illustrated in FIG. 7, the display control unit 110 can display thumbnails 1A and 1B corresponding to content belonging to a group “NEW” as a bundle and display the group name “NEW” above the thumbnails 1A and 1B. Further, the display control unit 110 can display thumbnails 1C and 1D corresponding to content belonging to a group “Recommend” as a bundle and display the group name “Recommend” above the thumbnails 1C and 1D. An object indicating the group may also be, for example, an image.

Thus, according to the first modification example of the embodiment, the display control unit 110 displays the thumbnails so that the user can recognize the group to which the content corresponding to the thumbnails belongs. Therefore, since the user can visually understand the group to which the content in the same category belongs, the efficient content retrieval is possible.

Further, the display control unit 110 displays the group name in the periphery of the thumbnails corresponding to the content belonging to the group. Therefore, since the user can understand the details of the group, the more efficient content retrieval is possible.

The foregoing group information can be generated by the content server 300. For example, the information processing apparatus 100 can record viewing information corresponding to viewed content and transmit the viewing information to the content server 300. Then, the content server 300 can generate the group information based on the viewing information received by the content server 300.

Specifically, the display control unit 110 stores the viewing information of the content in a storage unit or the like separately included in the information processing apparatus 100 and the server communication unit 106 transmits the viewing information to the content server 300. The viewing information includes, for example, content information of the content currently being viewed or viewing history of the content.

The content server 300 analyzes the received viewing information and generates the group information of the content. For example, the content server 300 can add information indicating that many viewers view content, e.g., a group name “Most Viewed”, to the group information in regard to the content which is determined to be viewed by many viewers at that time as the result obtained by analyzing the plurality of pieces of viewing information. The content server 300 can add information indicating recommendation, e.g., a group name “Recommend”, to the group information in regard to content which is determined to be a favorite of viewers based on a viewing history.

The foregoing group information can be generated through a registration operation on the content by the user. For example, the information processing apparatus 100 can include a separate registration unit (not illustrated). When the user performs the registration operation on the content, the registration unit can register, for example, a group name “Favorite” as group information to the content information of the content subjected to the registration operation.

The example in which the display control unit 110 displays the object indicating the group, e.g., the group name, has been described above. However, the display control unit 110 may not display the object and may allow a distance between the thumbnails corresponding to different groups to be greater than a distance of the thumbnails corresponding to the same group. For example, as illustrated in FIG. 7, the display control unit 110 can allow a distance between the thumbnails 1B and 1C corresponding to different groups to be greater than a distance between the thumbnails 1A and 1B corresponding to the same group. In this case, since an object such as a group name is not displayed, it is possible to improve visibility of the content being reproduced.

(Second Modification Example)

As a second modification example of the embodiment, in addition to the foregoing first modification example, the display control unit 110 may emphasize display of an object indicating a group to which content corresponding to a thumbnail subjected to a selection operation belongs when the operation detection unit 104 detects the selection operation of selecting the thumbnail. Specifically, when the operation detection unit 104 detects movement of the cursor 10, the display control unit 110 specifies a thumbnail closer to the display position of the cursor 10 than the other thumbnails and emphasizes display of a group name indicating a group corresponding to the thumbnail. For example, emphasized display of a group name will be described with reference to FIG. 8. FIG. 8 is a diagram illustrating emphasized display of a group name in the information processing apparatus 100 according to the second modification example of the present embodiment.

First, the display control unit 110 displays thumbnails and an object indicating a group corresponding to the thumbnails. For example, as illustrated in FIG. 8, the display control unit 110 displays the thumbnails 1A and 1B corresponding to the group “NEW” and the thumbnails 1C and 1D corresponding to the group “Recommend”.

Next, when the operation detection unit 104 detects movement of the cursor 10, the display control unit 110 specifies the thumbnail closer to the display position of the cursor 10 than the other thumbnails and emphasizes the display of the object indicating the group corresponding to the specified thumbnail. For example, when the operation detection unit 104 detects movement of the cursor 10, as illustrated in FIG. 8, the display control unit 110 moves the display position of the group name “NEW” of the group corresponding to the thumbnail 1A closer to the display position of the cursor 10 than the other thumbnails in the vertical direction by a predetermined amount. Thus, by moving the display position of the group name in the vertical direction by the predetermined amount, it is possible to prevent the cursor 10 and the group name from overlapping each other. The example in which the display control unit 110 moves the group name in the vertical direction by the predetermined amount has been described above. However, the display control unit 110 may change the group name itself or the size, the color, the shape, the luminance, or the like of the group name.

Thus, according to the second modification example of the embodiment, the display control unit 110 emphasizes the display of the object indicating the group to which the content corresponding to the thumbnail subjected to the selection operation belongs when the operation detection unit 104 detects the selection operation of selecting the thumbnail. Therefore, since the user can visually recognize the group corresponding to the selected thumbnail easily, it is possible to further improve the efficiency of the content retrieval.

(Third Modification Example)

As a third modification example of the embodiment, when the display control unit 110 moves thumbnails according to a user's operation detected by the operation detection unit 104, the display control unit 110 may move the succeeding thumbnails later than the earlier moved thumbnails. Specifically, after the display control unit 110 moves the displayed thumbnails in the vertical direction with respect to a direction in which the thumbnails are displayed at the time of switching of a category, the display control unit 110 displays the thumbnails corresponding to content belonging to a subsequently displayed category while moving the thumbnails in the vertical direction with respect to the direction in which the thumbnails are displayed. For example, a change in display of thumbnails at the time of switching of a category will be described with reference to FIG. 9. FIG. 9 is a diagram illustrating an example of a change in the display of the thumbnails at the time of switching of a category in the information processing apparatus 100 according to the third modification example of the present embodiment.

First, when the operation detection unit 104 detects a thumbnail display operation, the display control unit 110 displays a category name of a category set in initial display, and arranges and displays thumbnails corresponding to the category in one line. For example, as illustrated in the left drawing of the upper end of FIG. 9, the display control unit 110 can display the category name “Category 1” of the category set in the initial display, and arrange and display the thumbnails 1A to 1D corresponding to the category in the horizontal direction below the category name.

Next, when the operation detection unit 104 detects a category switching operation, the display control unit 110 erases the category name and the thumbnails while moving the displayed category name and thumbnails in the vertical direction with respect to the direction in which the thumbnails are displayed. For example, as illustrated in the middle drawing of the upper end of FIG. 9, when the operation detection unit 104 detects the category switching operation, the display control unit 110 erases the displayed category name “Category 1” and thumbnails 1A to 1D while moving the category name “Category 1” and the thumbnails 1A to 1D in the direction oriented toward the middle of the screen. Then, as illustrated in the right drawing of the upper end of FIG. 9, the category name “Category 1” and the thumbnails 1A to 1D are erased from the display screen. The display control unit 110 can gradually delay a movement speed of the category name and the thumbnails from start to end of the movement. In this case, by erasing the category name and the thumbnails so that aftereffects remain, it is possible to improve comfort of an operation provided to the user.

Next, the display control unit 110 displays a category name and thumbnails corresponding to a switching destination category while moving the category name and the thumbnails in the same direction as the movement direction of the category name and the thumbnails corresponding to the category before the switching. For example, as illustrated in the left drawing of the lower end of FIG. 9, the display control unit 110 displays a category name “Category 2” and thumbnails 2A to 2C corresponding to the switching destination category in the direction oriented toward the middle of the screen, after the thumbnails 1A to 1D corresponding to the category name “Category 1” before the switching are erased. At the time of the start of the display, the category name can be displayed to be smaller than the size of the category name displayed at the time of the end of the movement and can be displayed to be gradually enlarged according to a movement distance. Then, as illustrated in the right drawing of the lower end of FIG. 9, the display control unit 110 moves the category name “Category 2” and the thumbnails 2A to 2C up to the positions at which the category name and the thumbnails corresponding to the category before the switching are displayed.

Thus, according to the third modification example of the embodiment, the display control unit 110 moves the succeeding thumbnails by delaying the movement time with respect to the earlier moved thumbnails when the display control unit 110 moves the thumbnails according to the user's operation detected by the operation detection unit 104. Therefore, by impressing upon the user that the thumbnails are moved through the user's operation, it is possible to improve operability.

After the display control unit 110 moves the displayed thumbnails in the vertical direction with respect to the direction in which the thumbnails are displayed at the time of switching of the category, the display control unit 110 displays the thumbnails corresponding to content belonging to the subsequently displayed category while moving the thumbnails in the vertical direction with respect to the direction in which the thumbnails are displayed. Therefore, since a gap up to the display of the thumbnails or the like corresponding to the switching destination category is opened, it is possible to suggest to the user that the thumbnails displayed before the switching of the category and the thumbnails displayed after the switching of the category are different thumbnails corresponding to different categories.

(Fourth Modification Example)

As a fourth modification example of the embodiment, when the operation detection unit 104 detects a scrolling operation, the display control unit 110 may move the thumbnails in an opposite direction to a scrolling direction by delaying the thumbnails in the scrolling direction more than the thumbnails in the opposite direction to the scrolling direction. For example, a change in display of the thumbnails at the time of scrolling will be described with reference to FIG. 10. FIG. 10 is a diagram illustrating an example of a change in the display of the thumbnails at the time of scrolling in the information processing apparatus 100 according to the fourth modification example of the present embodiment.

First, when the operation detection unit 104 detects movement of the cursor 10, the display control unit 110 determines whether the display position of the cursor 10 is located at an end region of the display screen. For example, when the operation detection unit 104 detects the movement of the cursor 10, the display control unit 110 acquires the display position of the cursor 10 illustrated in the left drawing of the upper end of FIG. 10 and determines whether the display position of the cursor 10 is at an end of the display screen with respect to a position of 10% of the length of the display screen in the length direction from the end of the display screen.

When the display control unit 110 determines that the display position of the cursor 10 is located at the end region of the display screen, the display control unit 110 moves the thumbnails in the opposite direction to the scrolling direction while delaying a speed at the time of start of the movement when the thumbnail is the thumbnail displayed at a more distant position in the scrolling direction. For example, the display control unit 110 determines that the display position of the cursor 10 is located at a right end region of the display screen and moves the thumbnails 1A to 1D by delaying the movement speed in order of the thumbnails 1A to 1D, as illustrated in the middle drawing of the upper end of FIG. 10.

Next, after starting to move the thumbnails, the display control unit 110 displays the subsequent thumbnail of the thumbnail closer to the end of the display screen in the scrolling direction than the other thumbnails in the arrangement order while moving the thumbnail in the opposite direction to the scrolling direction. For example, as illustrated in the right drawing of the upper end of FIG. 10, after starting to move the thumbnail 1D closer to the end of the display screen in the scrolling direction than the other thumbnails, the display control unit 110 can display the subsequent thumbnail 1E of the thumbnail 1D while moving the subsequent thumbnail 1E in the opposite direction to the scrolling direction.

Next, when the operation detection unit 104 detects movement of the cursor 10, the display control unit 110 determines whether the display position of the cursor 10 is located at an end region of the display screen. For example, when the operation detection unit 104 detects the movement of the cursor 10, the display control unit 110 acquires a display position of the cursor 10 illustrated in the left drawing of the lower end of FIG. 10 and determines whether the display position of the cursor 10 is at an end of the display screen with respect to the position of 10% of the length of the display screen in the length direction from the end of the display screen.

When the display control unit 110 determines that the display position of the cursor 10 is not located at the end region of the display screen, the display control unit 110 stops the thumbnails in the order of the thumbnails in the opposite direction to the scrolling direction. For example, the display control unit 110 can determine that the display position of the cursor 10 is not located at the right end region of the display screen and can stop the thumbnail moved up to a stop position in the order of the thumbnails 1C to 1F, as illustrated in the middle drawing of the lower end of FIG. 10. Then, as illustrated in the left drawing of the lower end of FIG. 10, the display control unit 110 can stop the movement of all of the thumbnails and end the scrolling.

Thus, according to the fourth modification example of the embodiment, when the operation detection unit 104 detects the scrolling operation, the display control unit 110 moves the thumbnails in the opposite direction to the scrolling direction by delaying the thumbnails in the scrolling direction more than the thumbnails in the opposite direction to the scrolling direction. Therefore, by displaying the thumbnails so that the thumbnail is attracted to the other thumbnails to be moved or stopped, live movement is provided in the scrolling display, and thus it is possible to provide a comfortable operation to the user.

The example in which the display control unit 110 changes the speeds of the thumbnails at the time of the start of the movement according to the display positions of the thumbnails has been described. However, the display control unit 110 may change movement start times of the thumbnails according to the display positions of the thumbnails. For example, in the left drawing of the upper end of FIG. 10, the display control unit 110 can move the thumbnails by delaying the movement start time in the order of the thumbnails 1A to 1D. In this case, by further clarifying the delay of the movement of the thumbnail, the user can easily recognize this animation.

(Fifth Modification Example)

As a fifth modification example of the embodiment, the display control unit 110 may display the thumbnails by overshooting the movement of the thumbnails at the time of initial display of the thumbnails. Specifically, after the display control unit 110 displays the thumbnails while moving the thumbnails in a direction oriented toward the middle of the screen at the time of the initial display of the thumbnails, the display control unit 110 moves the thumbnails in a direction oriented away from the middle of the screen by a movement amount less than a movement amount in the direction oriented toward the middle of the screen. For example, a change in display at the time of the initial display of the thumbnails will be described with reference to FIG. 11. FIG. 11 is a diagram illustrating an example of a change in the display at the time of initial display of the thumbnails in the information processing apparatus 100 according to the fifth modification example of the present embodiment.

First, when the operation detection unit 104 detects a thumbnail display operation, the display control unit 110 starts displaying and moving the thumbnails. For example, as illustrated in the left drawing of FIG. 11, when the operation detection unit 104 detects a thumbnail display operation, the display control unit 110 displays the category name and the thumbnails 1A to 1D corresponding to the category “Category 1” set in the initial display while moving the category name and the thumbnails 1A to 1D in a direction oriented toward the middle of the screen.

Next, the display control unit 110 continuously moves the thumbnails to move the thumbnails up to positions a predetermined amount further in the direction oriented toward the middle of the screen than movement end positions of the thumbnails. For example, as illustrated in the left middle drawing of FIG. 11, the display control unit 110 continuously moves the thumbnails 1A to 1D, passes the movement end positions of the thumbnails, and further moves the thumbnails in the direction oriented toward the middle of the screen, as illustrated in the right middle drawing of FIG. 11.

Next, the display control unit 110 moves the thumbnails toward the movement end positions of the thumbnails and ends the movement of the thumbnails. For example, as illustrated in the left drawing of FIG. 11, the display control unit 110 can move the thumbnails 1A to 1D toward the movement end positions of the thumbnails in the opposite direction to the direction oriented toward the middle of the screen and end the movement of the thumbnails.

Thus, according to the fifth modification example of the embodiment, after the display control unit 110 displays the thumbnails while moving the thumbnails in the direction oriented toward the middle of the screen at the time of the initial display of the thumbnails, the display control unit 110 moves the thumbnails in the direction oriented away from the middle of the screen by the movement amount less than the movement amount in the direction oriented toward the middle of the screen. Therefore, since the thumbnails are displayed to protrude on the display screen, it is possible to provide a comfortable operation to the user.

(Sixth Modification Example)

As a sixth modification example of the embodiment, in addition to the foregoing fifth modification example, the display control unit 110 may display parts of the thumbnails displayed by switching a category corresponding to the thumbnails when the display control unit 110 overshoots the movement of the thumbnails. Specifically, when the display control unit 110 displays the thumbnails while moving the thumbnails in the direction oriented toward the middle of the screen at the time of the initial display of the thumbnails, the display control unit 110 temporarily displays the parts of the thumbnails corresponding to content belonging to a category displayed by switching the first category after the initial display. For example, a change in the display at the time of the initial display of the thumbnails will be described with reference to FIG. 12. FIG. 12 is a diagram illustrating another example of a change in the display at the time of the initial display of the thumbnails in the information processing apparatus 100 according to the sixth modification example of the present embodiment.

First, when the operation detection unit 104 detects a thumbnail display operation, the display control unit 110 starts display and movement of the thumbnails. Since the details are substantially the same as those of the fifth modification example, the description will be omitted.

Next, the display control unit 110 continuously moves the thumbnails to move the thumbnails up to positions a predetermined amount further in the direction oriented toward the middle of the screen than the movement end positions of the thumbnails. Here, the display control unit 110 moves the thumbnails in the direction oriented toward the middle of the screen more than the movement end positions of the thumbnails and displays the parts of the thumbnails while moving the parts of the thumbnails displayed by switching the category corresponding to the thumbnails. For example, as illustrated in the left middle drawing of FIG. 12, the display control unit 110 can continuously move the thumbnails 1A to 1D past the movement end positions of the thumbnails. Then, as illustrated in the right middle drawing of FIG. 12, the display control unit 110 can move the thumbnails 1A to 1D further in the direction oriented toward the middle of the screen and can display the parts of the thumbnails 2A to 2C corresponding to the category displayed by switching the category, while moving the parts of the thumbnails 2A to 2C.

Next, the display control unit 110 moves the thumbnails toward the movement end positions of the thumbnails, moves the thumbnails displayed by switching the category in the same direction to erase the thumbnails from the display screen, and ends the movement of the thumbnails. For example, as illustrated in the left drawing of FIG. 12, the display control unit 110 can move the thumbnails 1A to 1D toward the movement end positions of the thumbnails located in the opposite direction to the direction oriented toward the middle of the screen, move the thumbnails 2A to 2D in the same direction to erase the thumbnails 2A to 2D from the display screen, and end the movement of the thumbnails.

Thus, according to the sixth modification example of the embodiment, when the display control unit 110 displays the thumbnails while moving the thumbnails in the direction oriented toward the middle of the screen at the time of the initial display of the thumbnails, the display control unit 110 temporarily displays the parts of the thumbnails corresponding to the content belonging to the category displayed by switching the first category after the initial display. Therefore, it is possible to show the user that there are the thumbnails corresponding to the category displayed by switching the category,

(Seventh Modification Example)

As a seventh modification example of the embodiment, the display control unit 110 may display a list of categories and change the displayed thumbnails to the thumbnails corresponding to a category selected from the list. Specifically, when the operation detection unit 104 detects an operation of displaying the list of the categories, the display control unit 110 displays the list of the categories. When the operation detection unit 104 detects an operation of selecting a category, the display control unit 110 displays thumbnails corresponding to the category subjected to the selection operation. For example, a change in the display of the thumbnails through the selection of the list of the category will be described with reference to FIG. 13. FIG. 13 is a diagram illustrating an example of a change in the display of the thumbnails through the selection of the list of the categories in the information processing apparatus 100 according to the seventh modification example of the present embodiment.

First, when the operation detection unit 104 detects a thumbnail display operation, the display control unit 110 displays a category name of the category set in the initial display, and arranges and displays the thumbnails corresponding to the category in one direction. For example, as illustrated in the left drawing of the upper end of FIG. 13, the display control unit 110 can display the category name “Category 1” of the category set in the initial display and can arrange and display the thumbnails 1A to 1D corresponding to the category in the horizontal direction below the category name.

Next, when the operation detection unit 104 detects an operation of selecting the category name, the display control unit 110 displays the list of the categories. For example, as illustrated in the middle drawing of the upper end of FIG. 13, when the operation detection unit 104 detects an operation of selecting the category name “Category 1”, the display control unit 110 displays the list of the categories so that the list of the categories overlaps the thumbnails and the content being reproduced. The example in which the operation of displaying the list of the categories is the operation of selecting the category name has been described above. However, the operation of displaying the list of the categories may be an operation of pressing a category switch button or the like. When the operation of selecting the category name is cancelled or the operation of selecting the category, as will be described below, is not performed for a predetermined time, the display control unit 110 may end the overlapping display of the list of the categories.

Next, when the operation detection unit 104 detects the operation of selecting the category from the list of the categories, the display control unit 110 switches the category. For example, when the operation detection unit 104 detects an operation of selecting the category “Category 2” illustrated in the middle drawing of the upper end of FIG. 13 from the list of the categories, the display control unit 110 starts a category switching process. Then, as illustrated in the right drawing of the upper end of FIG. 13, the display control unit 110 can erase the thumbnails 1A to 1D from the display screen, as illustrated in the left drawing of the lower end of FIG. 13, by gradually erasing the thumbnails 1A to 1D and the category name corresponding to the category “Category 1” before the switching while moving the thumbnails 1A to 1D and the category name. Thereafter, as illustrated in the middle drawing and the left drawing of the lower end of FIG. 13, the display control unit 110 can display the thumbnails 2A to 2C and the category name corresponding to the switching destination category “Category 2” while moving the thumbnails 2A to 2C.

Thus, according to the seventh modification example of the embodiment, the display control unit 110 displays the list of the categories and changes the displayed thumbnails to the thumbnails corresponding to the category selected from the list of the categories. Therefore, the user displays the thumbnails corresponding to a desired category without performing the category switching operation, and thus it is possible to improve convenience of an operation.
